Answer:
$18
Step-by-step explanation:
For an approximation, we can start by rounding the number. In this case, you're probably expected to round to the nearest 1. 90.32 rounds down because 3 is less than 5. This leaves us with 90.
A good way to approximate this is to figure out what 10% is. You can do this by sliding the decimal over one place value.
10% of 90 is 9
10% + 10% = 20%
So we can add our two 10%'s together to find 20%
9 + 9 = 18
$18 is the tip
(I checked our work with the actual numbers and it checks out as a good approximation)
90.32 x .2 = 18.06
We are asked to solve for the degree equivalent of the given 121 degrees 22' 36". In order for us to solve this, we need to know the conversion such as:
1 degree = 60 minutes
1 minute = 60 seconds
Solving 22' to degrees, we have it:
22' * (degrees / 60 minute) = 0.3667 degrees
Solving for 36" to minutes and then to degrees, we have it:
36" * (' / 60") = 0.6'
0.6' * (degrees / 60 minutes) = 0.01 degrees
We need to add all the results in degrees such as:
121 + 0.3667 + 0.01 = 121.3767 degrees
The answer is 121.38°.

Step-by-step explanation:
The repeating decimal of -⁷/9 is -0.7777777777777.......................
2(y-3) +18
That’s what it looks like
35.2ft
You can get this my multiplying the scale factor by the height. In this case you need to use the bottom number to multiply since you are going in reverse.
